Description
Adjustable screw-jack pedestals that carry paving slabs or decking above a flat roof, so the finished terrace sits level and free-draining without anything penetrating or resting directly on the waterproofing.
Supplied as a fixed-size pack for a given terrace area. These are standard stock packs, not made to measure - pick the pack that covers your area and order it.
What they do
- Lift paving or decking clear of the membrane, so water drains underneath instead of sitting on the roof
- Take up the roof's fall, so the terrace surface finishes level over a sloping deck
- Spread load across the roof rather than concentrating it on slab corners
- Sit loose on the membrane - no fixings, no penetrations, fully reversible
Pack sizes
- 10m² - approx. 30 pedestals
- 20m² - approx. 58 pedestals
- 30m² - approx. 85 pedestals
- 50m² - approx. 140 pedestals
Quantities are based on 600 x 600mm slabs at 600mm centres, with an allowance for perimeter and corner supports. Larger or irregular terraces may need more - measure your layout before ordering.
What else the job needs
A protection layer between the membrane and the pedestals on any roof that will take regular foot traffic, and slabs or decking to sit on top. See our EPDM Rubber Walkway Pads for membrane protection.
What it replaces
Bedding slabs directly onto the roof in mortar or on loose ballast, which traps water against the membrane, cannot be levelled over a fall, and has to be broken out if the roof ever needs access.
